10 f-stops = a difference of 210 = 1024: 1 contrast ratio. 14 f-stops = a difference of 214 = 16,384: 1 contrast ratio. 16 f-stops = a difference of 216 = 65,536: 1 contrast ratio. 100,000:1 is normally regarded as approximately the range that the eye can see in a scene with no adaptation. 20 f-stops = a difference of 220 = 1,048,576: 1 contrast ratio. 1,000,000:1 is normally regarded as approximately the range that the eye can see in a scene with minimal (no noticeable) adaptation.

For example, a light bulb can have more than 10,000 cd/m2, surfaces lit in the sunlight can have brightness upwards of hundreds of thousands of cd/m2, while the night sky can be 0.005 cd/m2 or lower.
